Hi, I have some persistent entities that need to be run on two separate JBoss servers. One of which is connected to an oracle database and the other connected to a mssql database. This causes problems with the database specific primary key generation and the only way I can find round it is to create separate bean instances for each server. Is there another way? Could I extend the @GeneratedValue class and provide fucntionality to check which database is used and then provide the correct implementation. Thanks.
